To all whom t'may concern:

Be itknown that ISHMAEL' G. UUTRIGHT and 'JoHN A. SHARES, citizens of the United States, residing at Buckhannon, in the county of Upshur and State of West Virginia, have invented certain new and useful Improvements in Metal Shade Slats, of which the following is a specification.

This invention relates to new and useful improvements in shade or curtain slats, the primary object of the invention being to provide a slat constructed of sheet metal.

I to provide a metallic slat formed by folding An important object of the invention is a strip of sheet metal and to so arrange the free longitudinal edges of the strip that they will not present sharp edges to damage the fabric with which the slat is associated.

Anotherobject of the invention is to provide a metallic slat which is light, strong and durable, inexpensive to manufacture and which will maintain the shade with which it is associated in a perfectly fiat condition whenunwound from its roller.

Other objects and advantages of the invention will become apparent during the course of the following description.

In the accompanying drawing forming a p art of the application and wherein like numerals are employed to designate like parts throughout the several views.

Figure l is a sideelevation of one end of the improved slat, a portion of a curtain shade and the hem thereof being shown in dotted lines,

Figure 2 is a transverse section of the same.

In the drawings wherein for the purpose of illustration is shown the preferred embodiment of the invention, the numeral 3 designates a portion of the ordinary cloth window shade having its lower edge provided with the usual hem 4: which provides the shade with a transversely extending pocket for the reception of a slat.

As well understood, a slat forms an in which can be'elfectively'overcome by metal lic slats constructed in the proper manner. The old wooden slats are in the first place" liable to break,-and when they are broken the fractured ends present very rugged projections which will eventually punch through the cloth fabric if such has not a1; ready occurred with the breaking of the- ,slat. Furthermore, thesewooden slats very often warp due to both dampness and lack Such warping wouldof course of'moisture. impair the neat appearance'which the ordinary window shades are capable of making when the slats are in perfect condition.

Other than thesepoints, it will be obvious that a wooden slat could not possibly be used for theater curtains and moving picture screens, whereas acomparatively light and durable metallic slat-would effectively serve the purpose. I

It is therefore withthese points in mind that the present slat has been devised. This slat is constructed from a strip 5 of sheet metal which is folded longitudinally as at 6 to present a relatively broad convex edge. By thus folding the strip, a pair of sides 7 and 8 are provided for the slat and these sides are disposed in converging relationship to meet in a longitudinal edge as clearly seen in Figure 2. Of course, it will be understood that the slat may be bent into any other cross sectional shapedesired,but in the present instance we have selected the shape illustrated and which conform, to the general outline of the Wooden slat now in use.

In order that the longitudinal edges of the strip will not present edges which willbreak through the cloth fabric of the shade, the longitudinal marginal edge of the' side 8 is bent over the free edge 10 of the side 7 where it meets the side 8. This will of course conceal the free edge 10 of the side 7,

and marginal edge 9 of the side v8 is caused to lie in close contact with the longitudinal marginal edge of the side 7. It will be noted that the marginal edge 9 extends a substantial distance upon the side 7 so that the free edge of the margin 9 will not present a cutting surface. By the particular manner in which the longitudinal mar ginal edges of the strip of sheet metal are associated, it will be seen that they will be securely interlocked and that there is no possibility of the sides of the slat spreading. It will also be appreciated that a hollow slat is provided by the present vention which; is, comparatively, light one which will non-break: under anycondition or i cut through the fabric shade, one which will not warp, anda slat which may be used with equal faciliti es and advantages in "both small type of curtain and one such as is used in theaters and in conjunction with moving picture screens.
